d4724213c8 regulator: dt-bindings: mt6357: Drop fixed compatible requirement
commit 9cfdd7752b upstream.

Some of the regulators on the MT6357 PMIC currently reference the
fixed-regulator dt-binding, which enforces the presence of a
regulator-fixed compatible. However since all regulators on the MT6357
PMIC are handled by a single mt6357-regulator driver, probed through
MFD, the compatibles don't serve any purpose. In fact they cause
failures in the DT kselftest since they aren't probed by the fixed
regulator driver as would be expected. Furthermore this is the only
dt-binding in this family like this: mt6359-regulator and
mt6358-regulator don't require those compatibles.

Commit d77e89b7b0 ("arm64: dts: mediatek: mt6357: Drop regulator-fixed
compatibles") removed the compatibles from Devicetree, but missed
updating the binding, which still requires them, introducing dt-binding
errors. Remove the compatible requirement by referencing the plain
regulator dt-binding instead to fix the dt-binding errors.

e5250b8619 dt-bindings: pwm: adi,axi-pwmgen: Fix clocks
[ Upstream commit e683131e64 ]

Fix a shortcoming in the bindings that doesn't allow for a separate
external clock.

The AXI PWMGEN IP block has a compile option ASYNC_CLK_EN that allows
the use of an external clock for the PWM output separate from the AXI
clock that runs the peripheral.

This was missed in the original bindings and so users were writing dts
files where the one and only clock specified would be the external
clock, if there was one, incorrectly missing the separate AXI clock.

The correct bindings are that the AXI clock is always required and the
external clock is optional (must be given only when HDL compile option
ASYNC_CLK_EN=1).

driver. At the lowest level, the atmel_serial driver is using
serial_mctrl_gpio lib to enable/disable the corresponding IRQs
accordingly.  The warning emitted by CONFIG_DEBUG_ATOMIC_SLEEP is due to
disable_irq (called in mctrl_gpio_disable_ms) being possibly called in
some atomic context (some tty drivers perform modem lines configuration
in regions protected by port lock).

Split mctrl_gpio_disable_ms into two differents APIs, a non-blocking one
and a blocking one. Replace mctrl_gpio_disable_ms calls with the
relevant version depending on whether the call is protected by some port
lock.

e7e30a4a37 x86/bugs: Make spectre user default depend on MITIGATION_SPECTRE_V2
[ Upstream commit 98fdaeb296 ]

Change the default value of spectre v2 in user mode to respect the
CONFIG_MITIGATION_SPECTRE_V2 config option.

Currently, user mode spectre v2 is set to auto
(SPECTRE_V2_USER_CMD_AUTO) by default, even if
CONFIG_MITIGATION_SPECTRE_V2 is disabled.

Set the spectre_v2 value to auto (SPECTRE_V2_USER_CMD_AUTO) if the
Spectre v2 config (CONFIG_MITIGATION_SPECTRE_V2) is enabled, otherwise
set the value to none (SPECTRE_V2_USER_CMD_NONE).

Important to say the command line argument "spectre_v2_user" overwrites
the default value in both cases.

When CONFIG_MITIGATION_SPECTRE_V2 is not set, users have the flexibility
to opt-in for specific mitigations independently. In this scenario,
setting spectre_v2= will not enable spectre_v2_user=, and command line
options spectre_v2_user and spectre_v2 are independent when
CONFIG_MITIGATION_SPECTRE_V2=n.

68d59e9ba3 x86/its: Enable Indirect Target Selection mitigation
commit f4818881c4 upstream.

Indirect Target Selection (ITS) is a bug in some pre-ADL Intel CPUs with
eIBRS. It affects prediction of indirect branch and RETs in the
lower half of cacheline. Due to ITS such branches may get wrongly predicted
to a target of (direct or indirect) branch that is located in the upper
half of the cacheline.

Scope of impact
===============

Guest/host isolation
--------------------
When eIBRS is used for guest/host isolation, the indirect branches in the
VMM may still be predicted with targets corresponding to branches in the
guest.

Intra-mode
----------
cBPF or other native gadgets can be used for intra-mode training and
disclosure using ITS.

User/kernel isolation
---------------------
When eIBRS is enabled user/kernel isolation is not impacted.

Indirect Branch Prediction Barrier (IBPB)
-----------------------------------------
After an IBPB, indirect branches may be predicted with targets
corresponding to direct branches which were executed prior to IBPB. This is
mitigated by a microcode update.

Add cmdline parameter indirect_target_selection=off|on|force to control the
mitigation to relocate the affected branches to an ITS-safe thunk i.e.
located in the upper half of cacheline. Also add the sysfs reporting.

When retpoline mitigation is deployed, ITS safe-thunks are not needed,
because retpoline sequence is already ITS-safe. Similarly, when call depth
tracking (CDT) mitigation is deployed (retbleed=stuff), ITS safe return
thunk is not used, as CDT prevents RSB-underflow.

To not overcomplicate things, ITS mitigation is not supported with
spectre-v2 lfence;jmp mitigation. Moreover, it is less practical to deploy
lfence;jmp mitigation on ITS affected parts anyways.

6ea2e8743e platform/x86: msi-wmi-platform: Workaround a ACPI firmware bug
commit baf2f2c2b4 upstream.

The ACPI byte code inside the ACPI control method responsible for
handling the WMI method calls uses a global buffer for constructing
the return value, yet the ACPI control method itself is not marked
as "Serialized".
This means that calling WMI methods on this WMI device is not
thread-safe, as concurrent WMI method calls will corrupt the global
buffer.

Fix this by serializing the WMI method calls using a mutex.

686d8f7b59 arm64/boot: Enable EL2 requirements for FEAT_PMUv3p9
commit 858c7bfcb3 upstream.

FEAT_PMUv3p9 registers such as PMICNTR_EL0, PMICFILTR_EL0, and PMUACR_EL1
access from EL1 requires appropriate EL2 fine grained trap configuration
via FEAT_FGT2 based trap control registers HDFGRTR2_EL2 and HDFGWTR2_EL2.
Otherwise such register accesses will result in traps into EL2.

Add a new helper __init_el2_fgt2() which initializes FEAT_FGT2 based fine
grained trap control registers HDFGRTR2_EL2 and HDFGWTR2_EL2 (setting the
bits nPMICNTR_EL0, nPMICFILTR_EL0 and nPMUACR_EL1) to enable access into
PMICNTR_EL0, PMICFILTR_EL0, and PMUACR_EL1 registers.

Also update booting.rst with SCR_EL3.FGTEn2 requirement for all FEAT_FGT2
based registers to be accessible in EL2.

1f6916c554 netlink: specs: rt-link: adjust mctp attribute naming
[ Upstream commit beb3c5ad88 ]

MCTP attribute naming is inconsistent. In C we have:
    IFLA_MCTP_NET,
    IFLA_MCTP_PHYS_BINDING,
         ^^^^

but in YAML:
    - mctp-net
    - phys-binding
      ^
       no "mctp"

It's unclear whether the "mctp" part of the name is supposed
to be a prefix or part of attribute name. Make it a prefix,
seems cleaner, even tho technically phys-binding was added later.

15baba1095 netlink: specs: ovs_vport: align with C codegen capabilities
[ Upstream commit 747fb8413a ]

We started generating C code for OvS a while back, but actually
C codegen only supports fixed headers specified at the family
level right now (schema also allows specifying them per op).
ovs_flow and ovs_datapath already specify the fixed header
at the family level but ovs_vport does it per op.
Move the property, all ops use the same header.

This ensures YNL C sees the correct hdr_len:

   const struct ynl_family ynl_ovs_vport_family =  {
          .name           = "ovs_vport",
  -       .hdr_len        = sizeof(struct genlmsghdr),

b1e0b4f494 ata: libata-core: Add 'external' to the libata.force kernel parameter
[ Upstream commit deca423213 ]

Commit ae1f3db006 ("ata: ahci: do not enable LPM on external ports")
changed so that LPM is not enabled on external ports (hotplug-capable or
eSATA ports).

This is because hotplug and LPM are mutually exclusive, see 7.3.1 Hot Plug
Removal Detection and Power Management Interaction in AHCI 1.3.1.

This does require that firmware has set the appropate bits (HPCP or ESP)
in PxCMD (which is a per port register in the AHCI controller).

If the firmware has failed to mark a port as hotplug-capable or eSATA in
PxCMD, then there is currently not much a user can do.

If LPM is enabled on the port, hotplug insertions and removals will not be
detected on that port.

In order to allow a user to fix up broken firmware, add 'external' to the
libata.force kernel parameter.

libata.force can be specified either on the kernel command line, or as a
kernel module parameter.

For more information, see Documentation/admin-guide/kernel-parameters.txt.

a24a26adba Documentation: rust: add coding guidelines on lints
commit 139d396572 upstream.

In the C side, disabling diagnostics locally, i.e. within the source code,
is rare (at least in the kernel). Sometimes warnings are manipulated
via the flags at the translation unit level, but that is about it.

In Rust, it is easier to change locally the "level" of lints
(e.g. allowing them locally). In turn, this means it is easier to
globally enable more lints that may trigger a few false positives here
and there that need to be allowed locally, but that generally can spot
issues or bugs.

Thus document this.

4204ca15ec arm64: Filter out SVE hwcaps when FEAT_SVE isn't implemented
commit 064737920b upstream.

The hwcaps code that exposes SVE features to userspace only
considers ID_AA64ZFR0_EL1, while this is only valid when
ID_AA64PFR0_EL1.SVE advertises that SVE is actually supported.

The expectations are that when ID_AA64PFR0_EL1.SVE is 0, the
ID_AA64ZFR0_EL1 register is also 0. So far, so good.

Things become a bit more interesting if the HW implements SME.
In this case, a few ID_AA64ZFR0_EL1 fields indicate *SME*
features. And these fields overlap with their SVE interpretations.
But the architecture says that the SME and SVE feature sets must
match, so we're still hunky-dory.

This goes wrong if the HW implements SME, but not SVE. In this
case, we end-up advertising some SVE features to userspace, even
if the HW has none. That's because we never consider whether SVE
is actually implemented. Oh well.

Fix it by restricting all SVE capabilities to ID_AA64PFR0_EL1.SVE
being non-zero. The HWCAPS documentation is amended to reflect the
actually checks performed by the kernel.

On x86 the ranges are read from ACPI through driver-specific tables.
The built-in ranges are not necessarily correct, or may grow stale if an

Add a quirk infrastructure with which the minimum valid backlight value
can be maintained as part of the kernel.

This happens because the only async polling without interrupts that
iaa_crypto currently implements is with the 'sync' mode. With 'async',
iaa_crypto calls to compress/decompress submit the descriptor and return
-EINPROGRESS, without any mechanism in the driver to poll for
completions. Hence callers such as test_acomp() in crypto/testmgr.c or
zswap, that wrap the calls to crypto_acomp_compress() and
crypto_acomp_decompress() in synchronous wrappers, will block
indefinitely. Even before zswap can notice this problem, the crypto
testmgr.c's test_acomp() will fail and prevent registration of
"deflate-iaa" as a valid crypto acomp algorithm, thereby disallowing the
use of "deflate-iaa" as a zswap compress (zswap will fall-back to the
default compressor in this case).

To fix this issue, this patch modifies the iaa_crypto sync_mode set
function to treat 'async' equivalent to 'sync', so that the correct and
only supported driver async polling without interrupts implementation is
enabled, and zswap can use 'deflate-iaa' as the compressor.

Hence, with this patch, this is what will happen:

echo async > /sys/bus/dsa/drivers/crypto/sync_mode
cat /sys/bus/dsa/drivers/crypto/sync_mode
sync

There are no crypto/testmgr.c test_acomp() errors, no call traces and zswap
can use 'deflate-iaa' without any errors. The iaa_crypto documentation has
also been updated to mention this caveat with 'async' and what to expect
with this fix.

True iaa_crypto async polling without interrupts is enabled in patch
"crypto: iaa - Implement batch_compress(), batch_decompress() API in
iaa_crypto." [1] which is under review as part of the "zswap IAA compress
batching" patch-series [2]. Until this is merged, we would appreciate it if
this current patch can be considered for a hotfix.

2f5d37e92d dt-bindings: mfd: bd71815: Fix rsense and typos
[ Upstream commit 6856edf7ea ]

The sense resistor used for measuring currents is typically some tens of
milli Ohms. It has accidentally been documented to be tens of mega Ohms.
Fix the size of this resistor and a few copy-paste errors while at it.

Drop the unsuitable 'rohm,charger-sense-resistor-ohms' property (which
can't represent resistors smaller than one Ohm), and introduce a new
'rohm,charger-sense-resistor-micro-ohms' property with appropriate
minimum, maximum and default values instead.

Commit cdd30ebb1b ("module: Convert symbol namespace to string

leaving DEFAULT_SYMBOL_NAMESPACE as a macro expansion.

This commit converts DEFAULT_SYMBOL_NAMESPACE in the same way to avoid
annoyance for the default namespace as well.

The "regulator-compatible" property has been deprecated since 2012 in
commit 13511def87 ("regulator: deprecate regulator-compatible DT

regulator bindings YAML file. It should not have been used for new

f40881bde8 fs/writeback: convert wbc_account_cgroup_owner to take a folio
[ Upstream commit 30dac24e14 ]

Most of the callers of wbc_account_cgroup_owner() are converting a folio
to page before calling the function. wbc_account_cgroup_owner() is
converting the page back to a folio to call mem_cgroup_css_from_folio().

Convert wbc_account_cgroup_owner() to take a folio instead of a page,
and convert all callers to pass a folio directly except f2fs.

Convert the page to folio for all the callers from f2fs as they were the
only callers calling wbc_account_cgroup_owner() with a page. As f2fs is
already in the process of converting to folios, these call sites might
also soon be calling wbc_account_cgroup_owner() with a folio directly in
the future.

No functional changes. Only compile tested.
